THE RÔLE OF THYROXIN IODINE AND TOTAL ORGANIC IODINE IN THE CALORIGENIC ACTION OF WHOLE THYROID GLAND

Abstract
Assay of preparations of whole thyroid gland of which the thyroxin or so-called active I (the acid-insoluble fraction) had been determined showed that the calorigenic action of whole thyroid gland depends upon its total organic I not upon its thyroxin I content. The assays were conducted in cases of full-blown, spontaneous myxedema.
